This kit contains 180 tests and comes with 1 test solution, straightforward instructions, a glass test tube, and a color chart.

Phosphate can find its way into your aquarium through various sources such as tap water, fish droppings, and decomposing materials like leftover food and dead algae. An excess of phosphate can lead to unwanted algae growth and green water blooms, and in saltwater environments, high phosphate levels can hinder the development of hard corals. The API® PHOSPHATE TEST KIT measures phosphate concentrations ranging from 0 to 10 ppm, enabling you to effectively keep track of your aquarium's water quality. It is suitable for use in both freshwater and saltwater aquariums. This kit includes 150 tests along with 2 testing solutions, straightforward instructions, a glass test tube, and 2 color charts for your convenience.
